The two studied a metal alloy of iron and nickel called Invar, which is known for its low coefficient of thermal expansion. Invar was discovered in 1896 by Swiss physicist Charles Édouard ...

Using advanced computer simulations, the researchers analyzed the invar effect in detail and developed a pyrochlore magnet—an alloy with improved thermal expansion properties compared to invar. Metal ...

For this reason, the search has long been on for materials that always have the same length regardless of the temperature. Invar, for example, an alloy of iron and nickel, is known for its extremely ...

Invar, for example, an alloy of iron and nickel, is known for its extremely low thermal expansion. How this property can be explained physically, however, was not entirely clear until now.

A research collaboration has created a pyrochlore magnet alloy with near-zero thermal expansion, outperforming Invar. This breakthrough, based on advanced computer simulations, stabilizes materials ...
